Kamp C just became the first in the world to 3D print a two-story house in one piece, using the largest 3D printer in Europe.

The house in Westerlo, Belgium, is a demo for this style of 3D printing, showing off different styles. It's also a way to measure how the home, which was built using greener practices than typical constructions, holds up over time.

Kamp C's 3D printed house is part of the European C3PO project, supported by the European Regional Development Fund. The project brings together scientists and business people to advance 3D printing in Flanders.

Kamp C used a 3D printer to print a two story, 968 square foot house.

The massive 3D printer is the biggest in all of Europe.

The house is two floors, a first and a breakthrough in the world of 3D printed construction.

"The homes that have already been printed worldwide have only one floor and are often in parts factory printed and assembled on site. We have printed the entire building envelope as a whole on the site," project manager Emiel Ascione said.
